Abstract
Objective: To explore the clinical and genetic characteristics of asparagine synthase deficiency. Methods: Case series studies. Retrospective analysis and summary of the clinical data of 6 cases with asparagine synthase deficiency who were diagnosed by genetic testing and admitted to the Third Affiliated Hospital of Zhengzhou University from May 2017 to April 2023 were analyzed retrospectively. The main clinical features, laboratory and imaging examination characteristics of the 6 cases were summarized, and the gene variation sites of them were analyzed. Results: All of the 6 cases were male, with onset ages ranging from 1 month to 1 year and 4 months. All of the 6 cases had cognitive and motor developmental delay, with 3 cases starting with developmental delay, 3 cases starting with convulsions and later experiencing developmental arrest or even regression. All of 6 cases had epilepsy, in whom 2 cases with severe microcephaly developed epileptic encephalopathy in the early stages of infancy with spasms as the main form of convulsions, 4 cases with mild or no microcephaly gradually evolved into convulsions with no fever after multiple febrile convulsions with focal seizures, tonic clonic seizures and tonic seizure as the main forms of convulsions. Three cases of 4 gradually developed into stagnation or even regression of development and ataxia after multiple convulsions with no fever. There were normal cranial imaging in 2 cases, dysplasia of the brains in 1 cases, frontal lobe apex accompanied by abnormal white matter signal in the frontal lobe and thin corpus callosum in 1 case, thin corpus callosum and abnormal lateral ventricular morphology in 1 case, and normal in early stage, but gradually developing into cerebellar atrophy at the age of 5 years and 9 months in 1 case. Two cases underwent visual evoked potential tests, the results of which were both abnormal. Three cases underwent auditory evoked potential examination, with 1 being normal and 2 being abnormal. All of 6 cases had variations in the asparagine synthase gene, with 2 deletion variations and 7 missense variations. The variations of 2 cases had not been reported so far, including c.1341_1343del and c.1283A>G, c.1165_1167del and c.1075G>A. The follow-up time ranged from 3 months to 53 months. Two cases who had severe microcephaly died in infancy, while the other 4 cases with mild or no microcephaly were in survival states until the follow-up days but the control of epilepsy was poor. Conclusions: Asparagine synthase deficiency has a certain degree of heterogeneity in clinical phenotype. Children with obvious microcephaly often present as severe cases, while children with mild or no microcephaly have relatively mild clinical manifestations. The variation of asparagine synthetase gene is mainly missense variation.

Abstract
Objective: To explore the clinical manifestations and genetic characteristics of patients with epilepsy and episodic ataxia caused by SCN2A gene variation. Methods: The clinical data of seizure manifestation, imaging examination and genetic results of 5 patients with epilepsy and (or) episodic ataxia because of SCN2A gene variation admitted to the Department of Pediatrics, the Third Affiliated Hospital of Zhengzhou University from July 2017 to January 2021 were analyzed retrospectively. Results: Among 5 patients, 4 were female and 1 was male. The onset age of epilepsy ranged from 4 days to 8 months. There were 2 cases of benign neonatal or infantile epilepsy and 3 cases of epileptic encephalopathy, in whom 1 case had development retardation,1 case transformed from West syndrome to infantile spasm and another one transformed from infantile spasm to Lennox-Gastaut syndrome. One case of benign neonatal-infantile epilepsy was characterized by neonatal onset seizures and episodic ataxia developed at the age of 78 months. Electroencephalograms at first visit of 5 cases showed that 2 cases were normal, 1 case had focal epileptic discharge, and 2 cases had multi-focal abnormal discharge with peak arrhythmia. The brain magnetic resonance imaging (MRI) of 3 cases were nomal, 1 case was abnormal (brain atrophy with decreased white matter) and the results of 1 case was unknown. The follow-up time ranged from 17 months to 89 months. Four cases of epilepsy were controlled and 1 case died at 2 years of age. Two cases had normal intelligence and motor development, 2 had moderate to severe intelligence retardation and motor critical state, and 1 had moderate to severe intelligence and motor development retardation. SCN2A gene variations were identified in all cases. There were 4 missense variations and 1 frameshift variation. Three variations had not been reported so far, including c.4906A>G,c.3643G>T,c.638delT. Conclusions: Variations in SCN2A gene can cause benign neonatal or infantile epilepsy and epileptic encephalopathy. Some children develop episodic ataxia with growing age. The variation of SCN2A gene is mainly missense variation.

Abstract
Asbestos is classified as a Class 1 carcinogen by the International Cancer Organization (IARC) , and almost all types of asbestos are carcinogenic. The clinical data of 30 asbestos-induced occupational tumor patients in Qingdao city from January 2002 to May 2019 were analyzed, including 24 cases of asbestos-induced lung cancer and 6 cases of asbestos-induced malignant mesothelioma. Mesothelioma was significantly worse than lung cancer in terms of malignancy, the survival time of patients is shorter, and the mortality rate was higher. Both its diagnostic methods and treatment methods should be improved. The high incidence of asbestos-caused tumors is coming. It is recommended that workers exposed to asbestos dust should undergo regular chest CT examinations for early detection, early diagnosis and early treatment.

Abstract
Objective: To explore the clinical effect of traditional Chinese medicine (TCM) syndrome differentiation in the treatment of pneumoconiosis. Methods: We selected 160 pneumoconiosis patients who were hospitalized in our hospital from July 2015 to July 2016. 102 patients were divided into experimental groups, and the other 58 patients were assigned to the control group. These patients were randomly assigned. The control group was given routine treatment, while the experimental group received conventional treatment combined with TCM syndrome differentiation. We rated patients' quality of life using the SF-36 Quality of Life Scale. C-reactive protein levels in both groups before and after treatment were detected by ELISA. Furthermore, we detected the expression levels of IL-6 mRNA and TGF-β mRNA in serum before and after treatment by RT-PCR.The analysis was performed with SPSS19.0 software. The normal distribution measurement data was expressed by Mean±SD, and the t-test was used for statistical analysis. Non-normal distribution measurement data were expressed as median(M) and interquartile range (P(25), P(75)), and non-parametric test was used for statistical analysis. Results: Compared with the control group, the readmission rate in the experimental group decreased within 3 months; The SF-36 quality of life score results of the two groups showed a statistically significant difference in BP, VT and RE (P<0.05);The levelofCRPdecreasedsignificantlyafter treatment in bothgroups,and thedifferencewasstatistically significant (P<0.05).Comparedwith thecontrolgroup, the levelsofIL-6mRNAandTGF-β1mRNA alsodecreased (P<0.05). Conclusion: TCM syndromedifferentiation and treatmentofpneumoconiosis can effectively improve the patient's condition and life quality. We predict that it may inhibit the progression of pulmonary fibrosis in pneumoconiosis.

Abstract
Objective:To systemically evaluate the clinical significance of continuous transfixion suture for nasal septum in septoplasty. Method:Forty patients with nasal septum deviation were randomly assigned to the suture group including 20 patients who underwent endoscopic septoplasty followed by continuous transfixion suture for nasal septum, or the nasal packing group including 20 patients who underwent endoscopic septoplasty followed by nasal packing. Two groups were compared for the visual analogue scale (VAS) scores for postoperative rhinalgia, headache, lacrimation, dysphagia and sleep disorder, changes in mucociliary transport time (MTT) before and after surgery, and postoperative capillary hemorrhage. Patients were followed up for 2 weeks to observe the short-term postoperative complications. Result:Mean VAS scores for rhinalgia, headache, lacrimation, dysphagia and sleep disorder were all higher in nasal packing group than those in suture group (P<0.05); compared to suture group, there was greater prolongation of MTT before and after surgery in packing group (P<0.05); there was significant difference between two groups in postoperative capillary hemorrhage volume (P<0.05); in the nasal packing group, nasal synechia, nasal dryness and hyposmia were observed in 1, 3 and 2 patients, respectively, within 2 weeks postoperatively, whereas no short-term complications were observed in the suture group. Conclusion:Use of continuous transfixion suture in place of nasal packing following septoplasty can significantly improve the postoperative symptoms, protect nasal mucociliary clearance, and reduce short-term postoperative complications.

Abstract
Background American cockroaches (Periplaneta americana) are an important indoor allergen source and a major risk factor for exacerbations and poor control of asthma. We previously reported that allergen components from American cockroaches exhibit varying levels of pathogenicity. Sensitization to major American cockroach allergen, Per a 2, correlated with more severe clinical phenotypes among patients with allergic airway diseases. Materials and methods In this study, we examined whether oral plant vaccine-encoding full-length Per a 2 clone-996 or its hypoallergenic clone-372 could exert a prophylactic role in Per a 2-sensitized mice. The cDNAs coding Per a 2–996 and Per a 2–372 were inserted into TuMV vector and expressed in Chinese cabbage. Adult female BALB/c mice were fed with the cabbage extracts for 21 days and subsequently underwent two-step sensitization with recombinant Per a 2. Results Per a 2-specific IgE measured by in-house ELISA in the sera of Per a 2-372-treated groups were significantly lower than in the control groups after allergen challenge but not the Per a 2-996-treated group. Moreover, Per a 2–372 vaccine markedly decreased airway hyper-responsiveness and infiltration of inflammatory cells into the lungs, as well as reduced mRNA expression of IL-4 and IL-13 in comparison with the control mice. Conclusion Our data suggest that oral administration of edible plant vaccine encoding Per a 2 hypo-allergen may be used as a prophylactic strategy against the development of cockroach allergy.

Abstract
OBJECTIVE To investigate the expression of E-cadherin(E-cad), N-cadherin(N-cad), β-catenin(β-cat), which are the markers of Epithelial-mesenchymal transition and analyze their relationships with the clinicopathological features and the prognosis of the laryngeal squamous cell carcinoma. METHODS The expression levels of E-cad, N-cad, β-cat in 76 tumor tissues and their corresponding adjacent normal laryngeal tissues were determined by immunohistochemistry method. Relationships between the proteins' expression and clinicopathological features were analyzed. Survival curves were calculated using the Kaplan-Meier method. Differences in the survival rates were analyzed by the log-rank test among different expression groups. Cox's regression model was used to examine the independent predictor of the prognosis of the laryngeal cancer. RESULTS The expression levels of E-cad, N-cad, β-cat in tumor tissues and adjacent normal tissues were statistically significant(P<0.001). The expression level of E-cad and β-cat in the laryngeal carcinoma was related to lymph node metastasis, clinical pathological stage and differentiation degree (P<0.05), while N-cad expression level was associated with clinical stage and differentiation degree (P<0.05). The expression of E-cad was correlated with the expression of β-cat (P=0.001), and the expression of N-cad was correlated with β-cat (P=0.02), but the expression of E-cad was not correlated with N-cad. There were four subgroups of patterns of E-cad and N-cad expression: E-cad (+ )/N-cad (-), E-cad (+ ) /N-cad (+ ), E-cad (-) /N-cad (-), E-cad (-) /N-cad (+ ). The expression level of each group was related to the clinical pathological stage and differentiation degree (P<0.05). The expression level of E-cad/β-cat was associated with lymph node metastasis, clinical pathological stage and differentiation degree (P<0.01). Log-rank analysis showed that the prognosis of negative and positive groups was statistically different (P<0.05), and the combined analysis showed that the prognosis of E-cad/N-cad or E-cad/β-cat group was significantly different (P<0.01). Cox's regression model analysis showed that the clinical stage and β-cat were independent predictors of the prognosis of laryngeal carcinoma. CONCLUSIONS The low expression of E-cad, high abnormal expression of N-cad and β-cat played an important role in the occurrence and development of laryngeal carcinoma. It can provide a reference for evaluating clinical prognosis. The clinical pathological stage and β-cat can be used as independent predictors for the prognosis of laryngeal carcinoma.

Abstract
BACKGROUND Cockroaches are important sources of indoor airborne allergens. The American cockroach (Periplaneta americana) is the second leading inhalant allergen causing allergic airway diseases in Taiwan. We previously reported a difference in pathogenicity of different allergen components from American cockroaches. OBJECTIVE To analyze the environmental profile of American cockroach allergen components. METHODS Polyclonal antibodies were generated to recombinant American cockroach allergens, Per a 1 through Per a 10. The levels of each allergen in (1) whole-body extracts and feces from American cockroaches and in (2) fresh-frozen 6-month-old and 12-month-old dead American cockroaches were evaluated by immunoblotting and quantified. Levels of allergen components from patients' household dust samples were determined by competition enzyme-linked immunosorbent assay. RESULTS Per a 1, 2, and 10 proteins were present predominantly in roach feces, whereas other allergen components were found predominantly in roach bodies. There was a time-dependent decrease in total levels of some allergen proteins. Although levels of Per a 4, 5, 6, and 9 significantly decreased to less 20% of the basal level, there was no significant change in levels of Per a 2, 7, and 10 after 1-year decomposition. The most abundant allergen components in 20 dust samples from patients' houses were Per a 9, Per a 10, and Per a 2. CONCLUSION The concentration of 10 American cockroach allergen components differed in the environment. Per a 2 and Per a 10 can be used as markers of long-term environmental cockroach control and Per a 9 as current status of control in patients' houses.

Abstract
It is estimated that there are over ten million rare disease patients in China currently. Due to a lack of effective drugs and reimbursement regulations for medical expenses the diseases bring most patients enormous physical suffering and psychological despair. Past experience in other countries such as the United States, Japan, and the European Union have shown that legislation is the critical step to improve the miserable situation of rare disease patients. Laws and regulations for rare diseases in these countries prescribe a series of incentives for research and development of orphan drugs which turn out to obviously allow these drugs to flourish. Legislation has also established a drug reimbursement system to reduce the medical burden of the patients. These measures effectively protect the rights and interests of patients with rare diseases. In China, legislation for rare diseases has begun to attract the attention of authorities. It is anticipated that relevant laws and regulations will be established as early as possible to provide safeguards for rare disease patients in China.

Abstract
With the development of evidence-based medicine (EBM), the concept of "transfer of current best evidence into clinical decision-making" has garnered substantial attention worldwide. As such a good tool, many clinical practice guidelines (CPGs) for hepatocellular carcinoma (HCC) have been published worldwide under the guide of current best evidence. Our study did a systematic evaluation of the current 17 guidelines for HCC worldwide, which found that the appropriate constructing approach is the most important factor that influences guidelines implementation. Three factors of organizations or bodies drafting the guideline, exploration for achieving current best evidence, and purpose of constructing evidence-based CPGs for HCC should be paid close attention to. In order to achieve the current best evidence and promote evidence-based CPGs to be widely accepted and fully implemented, we recommend to conduct a systematic approach with 4 steps of global guidelines assessment, systematic literature review, experts' consensus and draft implementation, as well as implementation evaluation and periodic update in constructing and implementing evidence-based CPGs for HCC.

Abstract
Traditional Chinese medicine (TCM) is a typical traditional medicine (TM) with a long-standing history of preventing and curing diseases in China and other countries in East Asia. Standardization of TCM has been a topic of discussion over the past few decades in China with the goal of promoting advances in TCM in China and elsewhere around the world. Many quality and safety control standards for TCMs have been implemented in China, but systematic standards of efficacy have not been established for TCMs until now because of the absence of evidence from clinical practice. Evidence-based medicine (EBM) is the best way to provide evidence from clinical practice, but the quality of current EBM studies of TCM, and especially randomized controlled trials (RCTs) of TCM, needs to be improved. International registration of clinical trials (CTs) of TCM is a good way to provide quality evidence from clinical practice of TCM because it can improve research transparency and ultimately enhance the validity and value of scientific evidence. This evidence will provide the springboard for efforts to standardize TCM.

Abstract
Although important progress has been achieved in combating HIV/AIDs over the past 30 years, HIV/AIDs is still a serious threat to today's world. In China, figures on the incidence of this disease have painted a less than optimistic outlook. As the prevailing methods of preventing HIV/AIDS are all partially effective, novel and effective preventive interventions are needed in order to control the spread of the disease. Pre-exposure prophylaxis (PrEP) is one of the most promising prevention strategies and has garnered great attention worldwide. Current clinical trials on the efficacy and safety of this strategy have had some favorable results though major challenges around the world remain. Thus, China has taken an active part in the PrEP study to limit the prevalence of HIV/AIDS. This article describes the status of the PrEP study and discusses the opportunities and challenges encountered when implementing this strategy in China.

Abstract
Gastrointestinal cancer is a great threat to human health in Japan. Conventional anticancer therapies including surgery, radiation, and chemotherapy are the main strategies and play important roles in curing this disease or extending the life of patients with these cancers. On the other hand, patients undergo great suffering induced by these treatments. Kampo, the Japanese traditional medicine, has been used in clinics to reduce side effects and to improve the quality of life of gastrointestinal cancer patients in Japan. In order to testify to the efficacy and safety of these Kampo medicines and to clarify the underlying mechanisms, a number of clinical and basic studies were implemented in the past several decades. These studies suggested the benefits of Kampo medicine as an adjuvant to conventional anti-cancer therapies in treating gastrointestinal cancer. Since the safety and efficacy as well as quality control of traditional medicine have long been focused worldwide, the development course of Kampo medicine may provide reference to other countries in the world.
